LIving by Crystal River. Just went on the Constellation and did the Beaches of Normandy. We're in the 60+ range, but had a lot of younger people including a 12 year old boy on our bus. Numerous buses went there, and the ride was more like 2-1/2 hours 1 way, and a little over 2 the other. The countryside is just beautiful, and the Cemetary at Normandy is really something to see. Some of "Saving Private Ryan" was filmed there. Some friends did Paris and enjoyed the one that takes you on the Seine for lunch. Others said they were still treated badly in Paris, and they did Paris on their own.
Rental cars are not an option. If you want a car, it's a private excursion and must be booked before you leave. My husband doesn't particularly like buses, so he slept a little until I woke him up to see something.
